The Speaking Sonar Stick

Raspberry Pi + ultrasonics + voice synth = Aid 4 The Blind

In good experimental fashion, this project is a valuable study into what can be achieved with ‘commodity embedded technology’ like a Raspberry Pi. This ultrasonic distance measuring “robot” will greet you, measure distances to objects continuously and read the values out loud. It can also be programmed to activate alarms when the measured distance crosses a user-programmed limit. Got a pair of U/S distance sensors and an RPi ready? Then go.

Download the BOM list The BOM (Bill of Materials) is the technically exhaustive listing of parts and other hardware items used to produce the working and tested prototype of any Elektor Labs project. The BOM file contains deeper information than the Component List published for the same project in Elektor Magazine. If required the BOM gets updated directly by our lab engineers.
